Comparing sizing for the same tire

I'm thinking Goodyear Silent Armor's, but sizing is mind bending for me. I just don't quite get the subtle (or perhaps not so subtle differences):

P255/65R17
P255/70R17
P245/75R17
P235/70R17

I understand what the different measurements are, I just dont know how that translates to ride, stability, handling, etc...especially when comparing different sizes in the same tire, like above.

For example, would the 75 ride softer than the 65, because there's more tire (and more air) between the road and rim (and car)? WOuld the 255 be more stable at speed than the 235?

I get that the wider tire will do worse in rain and light snow, due to hydroplaning, and the wide tire should do better in sand and heavy snow, for the same exact reasons. It's more about understanding handling at speed, turning, ride comfort on pavement, and quietness of ride that I'm unclear on.

I'd appreciate any input you might have, plus this should probably be helpful to most noobs, like me!
